In order to analysis the performances of the marine crane and verify the stability of heave compensation control algorithm and examine the actual control effects, an experimental heave compensation system for marine crane had been built according to working principles and composition structure of real marine crane. This system is mainly composed of four parts which includes detecting system, driving system, control system and mechanical executive system. There are two control methods in the design of control system which includes DSP controller and MATLAB/Simulink platforms. The experimenters can pick up one of these controllers according to their demands. DSP controllers can also be used to the learning and development of embedded programming while MATLAB/Simulink platforms can be easily used to experimental tests with different control strategies. The common PID closed-loop control strategy, where the relative velocity between the cargo and the being supplied vessel can be got in the high frequency and low frequency sea conditions, is applied to this experimental system which verified the feasibility of this system effectively.
